Abstract
The energy contained in the blast furnace gas of a shaft furnace, particularly in the blast furnace gas of a cupola furnace, is utilized by wet cleaning the blast furnace waste gas as it emerges from the shaft furnace. The pre-treated blast furnace gas is then fed to a fine-dust filter for purification. Blast furnace gas entering the fine-dust filter is heated to the dew point by mixing it with a partial flow of purified gas branched off and heated upon exiting the fine-dust filter. Another portion of the purified gas mixture is fed to a gas turbine.
